Abstract

The invention provides a reloading method and device and a server. The method comprises the steps that identity information of an abnormal FPGA unit is determined; a position identifier of the FPGA unit is acquired according to the identity information; and the position identifier of the FPGA unit is sent to a BMC, so that the BMC performs a reloading operation on the FPGA unit according to the position identifier of the FPGA unit. According to the technical scheme provided by the invention, the position identifier of the FPGA unit is sent to the BMC, so that the BMC carries out reloading operation on the FPGA unit according to the position identifier. Therefore, even if the CPU cannot perform reloading operation on the FPGA unit, the FPGA unit can be reloaded through the BMC, and the reloading operation of the FPGA unit is realized by means of the I2C interface of the BMC, so that the FPGA unit can be recovered, and the normal use of the FPGA unit can be ensured.

Description

technical field [0001] The present application relates to the technical field of the Internet, in particular to a reloading method, device and server. Background technique [0002] With the development of communication technology, on the basis of devices such as PAL (Programmable Array Logic, programmable array logic), GAL (Generic Array Logic, general array logic), CPLD (Complex Programmable Logic Device, complex programmable logic device), FPGA (Field Programmable Gate Array, Field Programmable Gate Array) has been developed. FPGA can be used as a semi-custom circuit in the field of ASIC (Application Specific Integrated Circuit, Application Specific Integrated Circuit). FPGA can not only solve the deficiency of custom circuit, but also It can overcome the disadvantage of the limited number of gate circuits of the original programmable device. [0003] Under normal circumstances, multiple FPGA units can be deployed in the server, and the CPU (Central Processing Unit, centr...
